PROBLEM TO BE SOLVED: To provide apparatus and methods for providing a desired volumetrically conditioned airflow rate and for reducing a noise level, airflow recirculation and airflow separation.SOLUTION: An example apparatus includes a nozzle housing having a pair of opposing sidewalls 110 and a front wall 115 and a back wall 120 that define an airflow passage 125. The passage has a centerline 130 extending between an inlet 106 and an outlet 108 and has a plurality of cross-sections taken perpendicularly to the centerline that collectively define a smooth contour along a length of the passage. The cross-sections each have a thickness between the front and back walls that is greater at side edges than at the centerline. The thickness of the cross-sections decreases along a length of at least a first portion of the nozzle housing. A width of each of the cross-sections between the sidewalls increases along the length of at least the first portion of the nozzle housing.SELECTED DRAWING: Figure 2

    【課題】容積が調整された所望の空気流量を提供し、騒音レベル、気流の再循環、及び気流の剥離を低減させる、装置及び方法を提供する。【解決手段】例示的な装置は、空気流路125を画定する一対の対向する側壁110と前壁115及び裏壁120とを有する、ノズルハウジングを含む。流路は、入口106と出口108との間で延在する中心線130を有し、流路の長さに沿って滑らかな輪郭を集合的に画定する、中心線に対して垂直に切り取られた複数の断面を有する。断面は、各々、中心線よりも側端で大きい前壁と裏壁との間の厚さを有する。断面の厚さは、ノズルハウジングの少なくとも第1の部分の長さに沿って減少する。側壁の間の断面の各々の幅は、ノズルハウジングの少なくとも第1の部分の長さに沿って増加する。【選択図】図2
